I built a moving platform using Slider Frames to move some facades and the game crashes consistently when I try and stand on the moving parts.

funky-locomotion-1.12.2-1.1.1

Hi,
I have the same issue in "funky-locomotion-1.12.2-1.1.1". The same platform works well wiht "funky-locomotion-1.12.2-1.1.0.jar".
Error is:

I can reproduce this using just standard frame blocks. Being on the platform when it moves is a guaranteed crash.
